Innovations in “legacy sectors” of the economy – fossil fuels, manufacturing, buildings, transport, agriculture, the inter-state electric grid, health services delivery, higher education, and many others – are essential if we are to address major societal challenges like climate change, inequality, unemployment, competitiveness, and cybersecurity. Innovation in information technology, biotech, nanotech, and other frontier sectors won’t solve these long-standing problems in the absence of policy measures to overcome the obstacles that block innovation in legacy sectors. Yet we tend to focus innovation on frontiers, and are not good at bringing it to our legacy sectors. Charles Weiss and William B. Bonvillian offer ways to change directions on this with a new policy framework for delivering innovation in these areas. Join us for the discussion; much is at stake.
